. To all whom it may concern:

Be it known that I, EMIL W. SOHMELING, a citizen of the United States, residing at Rockford, in the county of WVinnebago and State of Illinois, have invented certain new and useful Improvements in Laboratory- Tables, of which the following is a specification.

This invention relates to tables and has more particular reference to working tables especially adapted for laboratory work, as for instance, in a domestic science laboratory.

One of the primary objects of my invention is to provide a table adapted for laboratory work, which will be of pleasing design and of simple and novel construction,

whereby the table may be manufactured at a low cost.

Another object ofmy invention is to provide a table of an improved construction, such that the table maybe shipped or trans ported knocked-down. and may be very readily and easily assembled or disassembled as the circumstances demand.

With these considerations in view, I have provided a table having a top equipped on its underside with slide members telescopingly mounted on a frame work comprising legs and side rails or braces connecting the same and holding them in spaced relation. The legs are constructed in a novel manner to provide simple and efficient means for telescopingly receiving the table-top 'slidemembers and for receiving the side braces or rails. Certain of the side rails are also of novel construction whereby to provide asimple means for rigidly" connecting the slide-members to the underside of the tabletop. These features and others which contribute to the purpose of. my invention will be more thoroughly understood by reference to the following description when considered ings, wherein;

Figure 1 is a view in perspective ofa in connection with the accompanying draw table embodying my improvements, a portion of one of the legs being shown in section; Fig. 2 is a fragmentary view in perspective showing the table top moved to a lowered position and also showing a portion of the top broken away; Fig. 3 is a plan sectional view taken through one of the slide-members inFig. 1; and Fig. 4; is a detail View in perspective illustrating the manner in which an UPPer section of a side 'connected by a single brace is connected to the table-top and a slide-member.

By reference to the drawings, it will be observed that the legs of the table, desig nated generally by reference characters 5 are substantlally square cross-sectionally and formed with a hollow center 6 extending to the top of the legs and being also square cross-sectionally. The legs may beheld in spaced relationand braced at'their lower portions by any suitable means, as for instance cross-bars-7, each connecting by mortise andtenon joints apair of legs and being cross-bar 8, as illus trated in Fig.1. The upper ends of thelegs are connected 1 together and braced by side braces or rails 9 and end braces or rails 11. The said rails or braces 9 and 11 are connected to the legs by means of dovetail Jointsas is clearly shown in Fig. 3, the ends of the side braces having dovetail tongues 12 fitting in dovetail grooves 13 cut in the legs. It will be observed that the grooves, 13 intersect the'hollow center of the legs thereby permitting the grooves to be very easily formed.

The table-top 14 is equipped on. its underside with slide-members 15-shaped to slide telescopingly within the legs. The slidemembers are rigidly connected to the table-- top through the intermediary of sections 16 which form the upper sections of the braces 11. The sections 16 may be fixedly con-. nected to the table-top by any suitable means, screws 17 being in the present instance used for the purpose, and a slidemember 15 is fixedly connected to each end of the this means the slide-membersare fixedly connected with the table-top. in a very simple andeflicient manner and without the use of metal angle braces or other more or less complicated and expensive fastening means such asare very commonly used for similar purposes. Itwill be observed that the braces 11 and 16 constitute, when the table-top is lowered, side braces substantially equivalent to side braces 9 with the exception that the former comprise two separable sections. As shown in Figs. 1 and 3, it is unnecessary to dovetail the ends of the braces 16 and the upper portions of the grooves in the legs which receive the same, since the dovetailed braces 11 suflice to rigidly connect and space the table legs.

sections 16 as shown in Fig. 4. By,

The slide-members 15 are 1w provided with a plurality of vertically spaced holes 18 adapted to receive pins 19, whereby the same may abut against the tops of the legs and hold the table-top in adjusted position. It is obvious that the tabletop may be adjusted vertically by changing" the pins to whatever holes are desired. The pins are attached by flexible cords 21 or any other suitable keeper devices to the braces 9 for the purpose of insuring that thepins will not be lost when removed from the slidemembers or when the table has'been disassembled for shipment or otherwise.

From the foregoing, it will be apparent that a table embodying my improvements may be very easily and quickly disassembled for the purpose of shipping or transporting, or having been shipped in knocked-down condition may 'be very easily assembled. When shipping, the slide-members 15 need not be detached from the sections 16, since by disconnecting the latter from the tabletop, the slide-members and sections 16 may be laid flat against the table-top in close relation with the several other parts. The disassembling of the remainder of the table structure is obvious, the side rails or braces 9 and 11 being removed by upward movement to withdraw their ends from the dovetail grooves in the legs and the lower bracing members 7 and 8 being withdrawn from their mortise and tenon connections in an apparent manner.

I claim: 1. A table comprising a top, legs, rails having dovetailed connection at thelr ends with the upper ends of the legs, certain of said rails being formed of separable upper and lower sections, the upper rail sections being fixedly connected to the underside of the table-top, vertically disposed slide-members fixedly connected to each upper rail section and being arranged to slidingly cooperate with the legs whereby the table-top is adjustably mounted vertically on the legs, and means for'holding the slide-members in adjusted position.

2. A table comprising a top, legs, side rails having dovetailed connection at their ends with the upper ends of the legs, end rails formed of separable upper and lower sections, said lower sections having dovetailed connection with the legs, but removable vertically with respect thereto, and said upper sections being fixedly connected to the underside of the table-top and at their ends loosely fitting in slots in the upper ends of the legs, so as to be freely movable vertically with respect to the legs vertically disposed slide-members connected rigidly to the said upper sections whereby the slidemembers are rigidly connected to the tabletop, the legs being constructed to slidingly receive said slide-members whereby the table-top is adjustably mounted vertically on said legs, and means, for holding the slide-members in adpisted position,
